Only duplicates screen does not Extend Screen. No Manufacturer or Support contact information
Reviewed in Canada on August 22, 2022
We purchase this because it advertised as MAC OS compatible. We wanted to be able to extend the computer screen to a second monitor. We followed the User Guide and installed the driver but the screen only duplicates onto the second screen. The User Guide indicates to "contact us by mail" and "contact us through the email address in our support letter included....". There is no mailing address, nor email address. There was no letter included with the device.
We could only duplicate the screen on a Levono laptop to Samsung Screen.
